The United States Patent and Trademark Office shows a trademark registration for the term "Shift" that was recently filed by Gearbox Software (thanks Kristian). From the looks of it, this is not for a game title, but rather a distribution network, with the implication that the developer is planning its own service in the style of Valve's Steam. Here's the description:

IC 042. US 100 101. G & S: Software as a service (SAAS) services featuring software for the management, transmission, storage and sharing of computer game programs and electronically stored information across computer networks

I sure hope they don't try to use Borderlands 2 as that game. Using Steamworks makes it the perfect blend of choclately addictive sci-fi Diablo and peanut buttery rich great digital service. I can't explain why exactly I am looking forward to Borderlands 2 so much or why I enjoyed the first so much; I just am and I just did.

Me too. I was way too late to the original, but I'm looking forward to playing some co-op with the Blues crowd in BL2.
